Description

Technical Field

[0001] The present invention relates to the technical field of automobile wiring harness terminal production, in particular to a multi-station bulk product automatic material receiving device. Background Art

[0002] Automotive wiring harness terminals are part of the automotive wiring harness, primarily used to connect the wires within it, ensuring stable current transmission between various electrical components. They tightly connect the conductor portion of the wire to the interface of other electrical equipment, forming a reliable electrical pathway. During production, automotive wiring harness terminals are typically punched and conveyed by a punch press before being collected and bagged. Due to the low efficiency of manual labor during bulk collection, circulating automatic bagging machines are currently used instead of manual bagging.

[0003] The current manual automatic material receiving machine has replaced manual material receiving and improved production efficiency. However, in the cyclic material receiving of the automatic material receiving machine, every time a group of barrels is filled and the barrel is replaced, the material receiving machine starts to rotate. At this time, if the punch press continues to discharge material, the conveying equipment may need to be paused and wait for the new barrel to rotate into place before it can be restarted to continue receiving material, resulting in the problem of discontinuity in the entire material receiving process, which in turn affects production efficiency. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem in the prior art that the entire material receiving process is still discontinuous, thereby affecting the production efficiency, and to propose a multi-station bulk product automatic material receiving device.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A multi-station automatic bulk material receiving device comprises a rotating base and a conveyor belt arranged on one side of the rotating base for receiving material discharged from a stamping machine; a rotating chassis is installed on the inner bottom of the rotating base, and a plurality of material receiving barrels are embedded in a circular array on the rotating base; a servo motor driving the rotating chassis is installed at the inner bottom end of the rotating base; a material guide plate is obliquely arranged at one end of the rotating base away from the conveyor belt; a transfer assembly for receiving material on the conveyor belt and conveying it to the material receiving barrel is installed on the inner top of the rotating base; a rotating discharge assembly for adjusting the material receiving volume of the material receiving barrel and conveying the material to the material guide plate is installed in the material receiving barrel;

[0007] An electric control box is provided on one side of the top surface of the rotating base, and a touch operation screen is installed on the electric control box. A first induction switch component and a second induction switch component are also provided between the rotating base and the rotating chassis. When the material receiving barrel moves to just above the material guide plate, the first induction switch component is turned on, and the electric control box controls the rotating discharge assembly to open the material receiving barrel to discharge the material. When the material receiving barrel follows the rotating chassis to move to just below the coaxial transfer assembly, the second induction switch component is turned on, and the electric control box controls the transfer assembly to move downward and discharge the material into the material receiving barrel.

[0008] Preferably, a bottom hole is opened at the center of the inner bottom of the rotating base, and a discharge hole is penetrated at the end of the inner bottom of the rotating base away from the conveyor belt. The receiving barrel is passed through from top to bottom, and the inner diameter is the same as the inner diameter of the discharge hole.

[0009] Preferably, a rotating shaft passing through the bottom hole is fixedly connected to the center of the bottom surface of the rotating chassis, and a plurality of mounting holes for mounting the material barrel are opened in a circular array on the outer side of the top surface of the rotating chassis, and the bottom end of the rotating shaft is connected to the output shaft of the servo motor.

[0010] Preferably, the first induction switch component includes a first fixed block arranged on one side of the bottom hole and a plurality of first induction blocks arranged on the bottom surface of the rotating chassis. The number of the first induction blocks corresponds to the material receiving barrel, and each first induction block corresponds to a rotary discharge assembly in the material receiving barrel. When the first induction block contacts the first fixed block, the electric control box controls the rotary discharge assembly to open the discharge.

[0011] Preferably, the second induction switch component includes a second fixed block arranged on one side of the bottom hole and multiple second induction blocks arranged on the bottom surface of the rotating chassis. The number of the second induction blocks corresponds to the material receiving barrel, and each second induction block corresponds to the transfer assembly. When the second induction block contacts the second fixed block, the electric control box controls the transfer assembly to move downward and start discharging.

[0012] Preferably, the transfer assembly includes a transfer box fixed on the inner top wall of the rotating base, a feed port opened at the upper end of one side surface of the transfer box, a bottom tube arranged at the bottom of the transfer box, and a discharge pipe located in the bottom tube. One end of the conveyor belt passes through the feed port to the transfer box, a first electric push rod is connected between the top end of the discharge pipe and the inner top wall of the transfer box, and an iris switch is installed at the bottom end of the discharge pipe, which is coaxially pressed above the receiving barrel.

[0013] Preferably, a pressure sensing ring for contact induction with the receiving barrel is provided on the outer side of the bottom surface of the iris switch, and a distance sensor aligned with the rotating discharge assembly is provided on the inner side of the bottom surface of the iris switch.

[0014] Preferably, the upper end of the transfer box is square and the lower end is funnel-shaped, and when the bottom end of the discharge pipe moves to contact the receiving barrel, the top end of the discharge pipe is flush with the top end of the bottom pipe.

[0015] Preferably, the rotary discharge assembly includes a supporting bottom ring fixedly mounted on the bottom end of the receiving barrel, a lifting upper ring located above the supporting bottom ring, a second electric push rod connected between the supporting bottom ring and the lifting upper ring, and two flip material plates symmetrically hinged on the inner side of the lifting upper ring, both sides of the bottom surface of the lifting upper ring are downwardly connected to an extension bottom rod, a third electric push rod is rotatably connected between one end of the bottom surface of the two flip material plates away from the hinge and the adjacent extension bottom rod, and a vibration motor is installed on the bottom surface of the two flip material plates.

[0016] Preferably, the length of the extended bottom rod is smaller than the length of the fixed end of the second electric push rod, and the inner diameter of the lifting upper ring is the same as the inner diameter of the supporting bottom ring.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] The present invention installs a rotating chassis, a servo motor, a receiving barrel and a transfer assembly on a rotating base, and provides a rotating discharge assembly in the receiving barrel. When a conveyor belt conveys automobile wiring harness terminals transmitted by a punch press, the transfer assembly can first pre-store the terminals and then sequentially rotate and discharge them into the receiving barrel, thereby realizing automatic material receiving and conveying, reducing manual labor and eliminating the need to stop the punch press, thereby improving production efficiency.

[0019] In addition, by installing a rotary discharge assembly in the receiving barrel, the flip material plate of the rotary discharge assembly rises and falls in the receiving barrel under the action of the second electric push rod, which can adjust the initial upper end volume in the receiving barrel, so that the volume of the material received by the receiving barrel can be freely adjusted according to the bagging specifications. When the customer requires different bagging specifications, there is no need for secondary packaging, which improves work efficiency and reduces labor intensity.

[0020] In addition, by setting the first induction switch component and the second induction switch component, the first induction switch component cooperates with the second induction switch component, so that when several receiving barrels move to the bottom of the transfer assembly, they automatically receive the material of the transfer assembly and move to the discharge position at the same time, and automatically open the rotary discharge assembly to discharge the material. The whole process does not require additional control and has a high degree of automation.

[0021] Finally, through the first electric push rod, discharge pipe, iris switch, distance sensor, pressure sensing ring and vibration motor of the rotary discharge assembly and the second electric push rod of the transfer assembly, when the transfer assembly discharges the material, the first electric push rod drives the discharge pipe to move to dock with the receiving barrel. First, the vibration motor maintains the uniform distribution of the material during automatic unloading, and then the distance sensor maintains the constant distance between the bottom pipe mouth of the discharge pipe and the flip material plate or the material on the flip material plate, which not only avoids the material being damaged during unloading due to excessive distance, but also avoids the problem of untimely vibration dispersion caused by excessive one-time discharge of the discharge pipe. At the same time, the unique setting of the discharge pipe and the transfer box can also achieve equal volume material receiving when the material is received in the receiving barrel.

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0037] Reference Figures 1-12A multi-station bulk product automatic receiving device comprises a rotating base 1 and a conveyor belt 2 arranged on one side of the rotating base 1 for receiving the discharge of the punching machine. After receiving the automobile wiring harness terminals conveyed by the punching machine, the conveyor belt 2 conveys the automobile wiring harness terminals to the inner side of the rotating base 1. A rotating chassis 3 is installed on the inner bottom of the rotating base 1, and a plurality of receiving barrels 4 are embedded in the rotating chassis 3 in a circular array. The rotating chassis 3 can drive the plurality of receiving barrels 4 to rotate with it. A servo motor 10 that drives the rotating chassis 3 is installed at the bottom end of the inner part of the rotating base 1. A guide plate 8 is arranged obliquely at the end of the inner part of the rotating base 1 away from the conveyor belt 2. A material receiving plate 8 for receiving the material on the conveyor belt 2 and conveying the material to the receiving plate is installed on the inner top of the rotating base 1. The transfer assembly 5 transported in the barrel 4 first stores the material transported by the conveyor belt 2, and then discharges it into the receiving barrel 4 in sequence after concentration, and the discharge efficiency of the transfer assembly 5 is greater than the efficiency of the conveyor belt 2 in transporting it to the transfer assembly 5, so as to ensure that when several receiving barrels 4 receive materials alternately, the conveyor belt 2 and the punch press do not need to be paused. The receiving barrel 4 is equipped with a rotating discharge assembly 9 for adjusting the material receiving volume of the receiving barrel 4 and transporting the material to the guide plate 8. Through the setting of the rotating discharge assembly 9, the material receiving volume of the upper end of the receiving barrel 4 can be adjusted, and then the volume size can be freely adjusted according to the bagging specifications. When the customer requires different bagging specifications, there is no need for secondary packaging, which improves work efficiency and reduces labor intensity.

[0038] An electric control box 6 is provided on one side of the top surface of the rotating base 1. The electric control box 6 controls the start and stop operation of all equipment and receives signals from several sensor devices. A touch operation screen 7 is installed on the electric control box 6. The touch operation screen 7 realizes the control operation of the electric control box 6. A first sensing switch and a second sensing switch are also provided between the rotating base 1 and the rotating chassis 3. The first sensing switch and the second sensing switch can be pressure sensing switches or photoelectric sensing switches, such as pressure sensors or photoelectric sensors. When the material receiving barrel 4 moves to just above the guide plate 8, the first sensing switch is turned on, and the electric control box 6 controls the rotating discharge assembly 9 to open the material receiving barrel 4 to discharge the material. When the material receiving barrel 4 moves to just below the coaxial transfer assembly 5, the second sensing switch is turned on, and the electric control box 6 controls the transfer assembly 5 to move downward and discharge the material into the material receiving barrel 4, so that the material receiving barrel 4 automatically receives the transferred material and then discharges it in a centralized manner during the process of following the rotation movement on the rotating chassis 3, thereby realizing fully automatic material collection.

[0039] Reference Figure 1-Figure 5A bottom hole 102 is opened at the center of the inner bottom of the rotating base 1, and the bottom hole 102 connects the inside and outside of the rotating base 1. A discharge hole 101 is penetrated at the end of the inner bottom of the rotating base 1 away from the conveyor belt 2. The receiving barrel 4 passes through from top to bottom, and the inner diameter is the same as the inner diameter of the discharge hole 101, so that the receiving barrel 4 can move to the top of the discharge hole 101 and be coaxially arranged when following the rotation of the rotating chassis 3, ensuring that the material discharged by the receiving barrel 4 enters the interior of the rotating base 1 through the discharge hole 101 and is transported to the next process through the guide plate 8.

[0040] Reference Figures 1-6 , a rotating shaft 302 passing through the bottom hole 102 is fixedly connected at the center of the bottom surface of the rotating chassis 3, and a plurality of mounting holes 301 for the material receiving barrel 4 are opened in a circular array on the outer side of the top surface of the rotating chassis 3. The material receiving barrel 4 is rotatably mounted in the rotating chassis 3 through the mounting holes 301. In the figure, the mounting holes 301 and the material receiving barrel 4 are both set to 8. The bottom end of the rotating shaft 302 is connected to the output shaft of the servo motor 10, so that the servo motor 10 drives the rotating shaft 302 to rotate, and then drives the rotating chassis 3 to rotate. And because there are 8 material receiving barrels 4, the servo motor 10 only rotates 45° each time and then stops, waiting for the next start.

[0041] Reference Figure 1-Figure 7 The first induction switch component includes a first fixed block 103 arranged on one side of the bottom hole 102 and a plurality of first induction blocks 303 arranged on the bottom surface of the rotating chassis 3. The number of the first induction blocks 303 corresponds to the material receiving barrel 4, and each first induction block 303 corresponds to a rotary discharge component 9 in the material receiving barrel 4, that is, only when the first induction block 303 contacts the first fixed block 103, the electric control box 6 controls the rotary discharge component 9 in the corresponding material receiving barrel 4 to open the discharge, thereby realizing automatic discharge of the material receiving barrel 4 moved to the discharge hole 101 without additional control.

[0042] The second sensing switch component includes a second fixed block 104 arranged on one side of the bottom hole 102 and a plurality of second sensing blocks 304 arranged on the bottom surface of the rotating chassis 3. The number of the second sensing blocks 304 corresponds to the material receiving barrel 4, and each second sensing block 304 corresponds to the transfer assembly 5. When the second sensing block 304 contacts the second fixed block 104, the electric control box 6 controls the transfer assembly 5 to move downward and start discharging materials. That is, during the rotation and movement of the material receiving barrel 4, whenever a second sensing block 304 contacts and senses the second fixed block 104, the transfer assembly 5 works once to complete the discharge of materials into the material receiving barrel 4. Here, the second sensing block 304 and the second fixed block 104, as well as the first sensing block 303 and the first fixed block 103 can refer to the transmitting end and the receiving end of the photoelectric sensor.

[0043] Reference Figure 1-Figure 3 and Figures 8-11The transfer assembly 5 includes a transfer box 51 fixed on the inner top wall of the rotating base 1, a feed port 52 opened at the upper end of one side surface of the transfer box 51, a bottom tube 53 arranged at the bottom of the transfer box 51, and a discharge pipe 54 located in the bottom tube 53. One end of the conveyor belt 2 passes through the feed port 52 to the transfer box 51, and the material produced by the punch press is directly discharged into the transfer box 51. A first electric push rod 56 is connected between the top of the discharge pipe 54 and the inner top wall of the transfer box 51. The first electric push rod 56 can be extended to drive the discharge pipe 54 to move in the transfer box 51. The iris switch 55 is a pipe valve structure composed of an iris mechanism. The maximum opening diameter of the iris switch 55 is coaxial with the inner tube diameter of the discharge pipe 54, so that when the discharge pipe 54 slides up and down, the iris switch 55 slides up and down on the outside of the transfer box 51. A motor is provided on one side of the iris switch 55 to drive it to open and close. When the motor rotates forward, it drives the iris switch 55 to open the discharge pipe 54. When the motor rotates backward, it drives the iris switch 55 to close the discharge pipe 54.

[0044] A pressure sensing ring 57 that senses contact with the receiving barrel 4 is provided on the outer side of the bottom surface of the iris switch 55. The pressure sensing ring 57 includes a soft shell and a pressure sensor arranged in the soft shell. The soft shell includes a rubber shell or a silicone shell. When the iris switch 55 contacts the top surface of the receiving barrel 4, the soft shell is compressed, and the pressure condition is received by the pressure sensor to determine that the iris switch 55 and the receiving barrel 4 are in contact. A distance measuring sensor 58 is provided on the inner side of the bottom surface of the iris switch 55, which is aligned with the rotary discharge assembly 9. After the iris switch 55 contacts the receiving barrel 4, the distance measuring sensor 58 can measure the distance between the bottom of the iris switch 55 and the top of the rotary discharge assembly 9, or measure the distance between the bottom of the iris switch 55 and the discharged automotive wiring harness terminals, so that during the discharge process, the height of the automotive wiring harness terminals after falling from the discharge pipe 54 can be kept as consistent as possible, and at the same time, it can be determined that the receiving barrel 4 is full of automotive wiring harness terminals.

[0045] Furthermore, in order to ensure that all the automobile wiring harness terminals in the transfer box 51 can be discharged into the discharge pipe 54, the upper end of the transfer box 51 is square and the lower end is funnel-shaped. When the bottom end of the discharge pipe 54 moves to contact the receiving barrel 4, the top of the discharge pipe 54 is flush with the top of the bottom tube 53, that is, when the first electric push rod 56 is extended to the maximum, at the same time, a groove is opened on the bottom wall of the transfer box 51 for the end of the first electric push rod 56 to fit in and be inserted into.

[0046] Reference Figure 4 and Figure 12The rotary discharge assembly 9 includes a supporting bottom ring 91 fixedly mounted on the bottom end of the receiving barrel 4, a lifting upper ring 92 located above the supporting bottom ring 91, a second electric push rod 93 connected between the supporting bottom ring 91 and the lifting upper ring 92, and two flip material plates 94 symmetrically hinged on the inner side of the lifting upper ring 92. Under the action of the second electric push rod 93, the lifting upper ring 92 can move up and down, and then cooperate with the flip material plate 94 to adjust the upper end space of the receiving barrel 4, that is, the material receiving volume. Both sides of the bottom surface of the lifting upper ring 92 are connected downwardly with an extended bottom Rod 95, the bottom surface of the two flip material plates 94 is away from the end of the hinge and is rotatably connected to the adjacent extended bottom rod 95 with a third electric push rod 96. When the third electric push rod 96 is extended and retracted, it can drive the two flip material plates 94 to rotate and open the material receiving barrel 4, and there is a gap between the two flip material plates 94 horizontally to ensure that it will not affect the subsequent downward rotation. The bottom surface of the two flip material plates 94 is installed with a vibration motor 97. When the flip material plates 94 receive the material, the vibration motor 97 can vibrate and disperse the automotive wiring harness terminals evenly. The length of the extended bottom rod 95 is less than the length of the fixed end of the second electric push rod 93 to ensure that when the second electric push rod 93 is retracted to the minimum, the extended bottom rod 95 will not touch the support bottom ring 91. The inner diameter of the lifting ring 92 is the same as the inner diameter of the support bottom ring 91, so that after the two flip material plates 94 rotate downward to expand the gap, the automotive wiring harness terminals pass through the gap and then pass through the support bottom ring 91 to be discharged from the material receiving barrel 4.

[0047] Working principle: Refer to Figures 1-12 When receiving the material, the conveyor belt 2 starts to convey the automobile wiring harness terminal box produced by the punch press into the transfer storage box 51. The terminals first enter the transfer storage box 51 for storage. The servo motor 10 rotates, driving the rotating chassis 3 to rotate, and the servo motor 10 rotates only 45 degrees each time, thereby causing the rotating chassis 3 to rotate 45 degrees each time, moving the empty receiving barrel 4 to the bottom of the transfer storage box 51, and moving the full receiving barrel 4 to the top of the discharge hole 101.

[0048] At this time, the first sensing block 303 contacts the first fixed block 103, and the first sensing switch starts to send a signal to the electric control box 6. After receiving the signal, the electric control box 6 controls the third electric push rod 96 in the receiving barrel 4 corresponding to the first sensing switch to retract. The third electric push rod 96 retracts, pulling the two flip material plates 94 to rotate downward. During the downward rotation of the two flip material plates 94, the gap between them gradually increases to the maximum. During this process, the automobile wiring harness terminals in the receiving barrel 4 begin to fall downward from the gap, pass through the unloading hole 101 and enter the guide plate 8, and enter the next process. After all the automobile wiring harness terminals in the receiving barrel 4 are unloaded, when the first sensing block 303 is out of contact with the first fixed block 103, the third electric push rod 96 is restored;

[0049] At the same time, the second sensing block 304 contacts the second fixed block 104, and the second sensing switch also sends a signal to the electric control box 6. The electric control box 6 controls the first electric push rod 56 to extend. The first electric push rod 56 extends, driving the discharge pipe 54 to move downward until the iris switch 55 at the bottom end of the discharge pipe 54 contacts the top surface of the receiving barrel 4 and touches the pressure sensing ring 57. At this time, the first electric push rod 56 extends to the maximum state and begins to pause. At the same time, after the pressure sensing ring 57 is squeezed, the second electric push rod 93 begins to extend and drives the two flip material plates 94 in the receiving barrel 4 just below the transfer assembly 5 upward. The distance measuring sensor 58 measures the distance from the flip material plate 94 to the bottom of the iris switch 55 in real time until it reaches the optimal automobile wiring harness terminal drop distance and stops. The iris switch 55 starts to open automatically, and the vibration motor 97 is turned on at the same time. The iris switch 55 opens the automobile wiring harness terminal in the discharge pipe 54 and drops downward. It falls onto the flip material plate 94 and is evenly distributed on the two flip material plates 94 under the vibration of the vibration motor 97. The distance sensor 58 measures the distance from the top automobile wiring harness terminal to the iris switch 55 at this time. When the distance becomes smaller, the second electric push rod 93 begins to shrink, so that the height of the automobile wiring harness terminal falling through the discharge pipe 54 remains consistent. Until the second electric push rod 93 shrinks to the required bagging height, it stops shrinking. At this time, the automobile wiring harness terminal continues to fall until the receiving barrel 4 is filled. The distance sensor 58 monitors in real time. When the filling requirement has been met, that is, the automobile wiring harness terminal has accumulated in the discharge pipe 54 and no longer falls, the iris switch 55 begins to close, and the first electric push rod 56 begins to shrink and recover, driving the discharge pipe 54 to recover upward. After recovering to the initial position, the servo motor 10 starts again at 45° to start the next group of receiving barrels 4 to fill the material and the receiving barrel 4 to discharge the material after it is full, and the cycle is repeated.
